STEAM-INJECTOR.

y SPECIFICATION forming part of Letters Patent No. 600,455, dated March 8, 1898. Application filed August 13, 1897- Serial No. 648,165. (Model.)

.To all whom, it muy concern:

Be it known that I, FRANCIS STICKER, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Steam-Injectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the ro same.

This invention contemplates certain new and useful improvements in steam-injectors, having reference particularly to the class known to the trade as locomotive or double-jet injectors.

In two concurrent applications for Letters Patent, filed July 29,1897, Serial Nos. 646,354 and 646,355, I have pointed out the advantages to be obtained from the employment of zo a single positively-operated cock for control ling the starting and working, including regulation, of a steam-injector, all valves, movable nozzles, and the like being dispensed with. In said applications I particularly pointed out the advantages of having no pressure to overcome in starting an injector other than that of the atmosphere, and also that not only does the single cock render the use of a check-valve unnecessary to avoid back 3o pressure from the boiler, but all communication between the boiler-outlet and the overilow is entirely avoided.

In the present invention Icontemplate the adaptation of a single positively-guided cock to a locomotive-injector, such cock controlling the overflow, the admission of steam, the working of the injector, the regulation thereof, and the passage to the boiler. In this class of injectors as used on locomotives and 4o steam vessels it is normally required that they be capable of sure and effective starting and working almost instantaneous, be entirely independent of any valves in the pipe connections, and be equipped with handle or lever mechanism for controlling a steam-valve for regulating the starting and working of the apparatus. Ordinarily in addition to the valves for controlling the admission of steam automatic valves in connection 5o with or independent of positively-operated valves have been employed for controlling or aecting the overflow. In addition to the wear on these valves caused by the steam it is Well known that the water, being of all sorts and descriptions, according to the different parts of the country, will soon effect a partial if not total destruction of all mov able parts, requiring their immediate replacement or the total abandonment of the use of the injector. Most of the water used is more 6o or less filled with dirt, lime, andthe like, and this, when the water attains a high velocity, will cause a constant grinding and wear on all the parts with which it contacts. Aside from the deleterious action of the steam and water on all the finely-worked elements of an injector the constant flow of steam and water through narrow valves, holes, or other contracted passages results in great loss from friction, consequently decreasing the power. 7o

`Vith all these difliculties in view I have produced an injector of the class mentioned in which they are successfully overcome.

The primary object of my invention is to control the admission of steam to the lifter and forcer by a single cock, which will also control the overflow.

Additional objects are, iirst, to dispense with all movable part-s for controlling the starting, working, and regulation of the ap 8o paratus other than a single cock; second, to so locate the tubes of the lifter and forcer that they will have a more suitable position to each other, conforming to the natural flow of water and steam; third, to provide for a direct flow of the steam and water to, through, and from the injector; fourth, combining all overiiows in one common chamber, and, fifth, to reduce the number of parts to a minimum and avoid all complications of construction. 9o

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

Fig. 3 is in part a plan View and in part a horizontal sectional view on line 8 3, Fig. 2. Fig. 4 is a l1oriz`ontal sectional View in part on line 4 4 and in part on line 4' 4', Fig. 2.

Fig. 7 is a vertical sectional view in part on line? 7 and in part on line 7' 7', Fig. 2. Fig. S is a diagrammatical View showing in eight different series the several positions occupied by the different portions of the cock. Figs. 9 and IO are outside views of the cock. Figs. l1 and l2 are sectional views on lines 11 1l and l2 12, respectively, Figs. 10 and 9.

Referring to the drawings, A designates the casing or casting; a, the steam-inlet; a', the water-inlet; CL2, the overow, and a3 the boileroutlet. The steam-inlet a is located at about the center of the casing, into which it opens and then leads rearward, opening into a vertical conical opening a4, which terminates in the overflow a2.

B is the lifter, which is located in the upper part of casing A. The position occupied by the lifter--that is, the line of travel induced by the several tubes-is the reverse of that heretofore employed. In other words, the direction of operation of the lifter is away from instead of toward the boiler outlet. The lifter comprises a steam-tube 19, combiningtube 19', and delivery-tube 192, the two latter tubes being integral. The steam-tube leads from a steam-chamber 193 and opens into a'water-chamber 194, into which projects the combining-tube. This water-chamber 194 communicates with the water-inlet a by a cored passage-way 195, one on each side of the casing. The delivery-tube 192 opens into a dischargechamber 196 at what is normally the receiving end of the apparatus. Steam is admitted to the steam-chamber 193 through side channels 197, running parallel with the inner horizontal branch of steam-inlet a. A horizontal partition 198, extended longitudinally within the casing, separates the lifter from direct communication with the lower portion of the casing. y

D is the forcer, the line or direction of operation of which is the reverse of that of the lifter. In other words, its feeding is directly toward the boiler-outlet. Of the forcer,dis the steam-tube, d the combining-tube, and d2 the delivery-tube. The steam-tube extends at its receiving end into a steam-chamber d3 and at its other end into a water-chamber C14, in which is also located the combiningtube. This water-chamber communicates with the discharge-chamber 19G of the lifter by cored passages d in each side of the casin g. Hence water discharged by the lifter will flow downward from chamber bi into the Water-chamber C14 of the forcer. This water-chamber d4 is formed with a lower elongation d6, terminating in an auxiliary overflow-openin g, said elongation forming the channel for the overow from the vlifter as well as that occurring at the mouth of the forcer combining-tube. The deliverytube d2 is mounted in a partition 117, forming a discharge-chamber d8 for the forcer. The

primary overiiow occurring at the end of this delivery-tube will pass out through the open end of this chamber d8 into the opening a4.

E is the forcer steam-channel, running longitudinally of the apparatus, being formed by the horizontal partition 198 and a lower corresponding partition e. This channel E eX- tends from the Yvertical opening a4 to and opens at its other end into the lsteam-chamber d3. Y

In practice steam is first admitted in a small quantity to the lifter, and after passing through the latter and down to the waterchamber of the forcer, and thence to the atmosphere, water is lifted. Vhile this is occurring no steam is admitted to the forcer, but instantly upon establishing the column a full head of steam is admitted to the forcer and also to the lifter, all overflows being positively closed. The capacity of the machine may be regulated by controlling the steamsupply to the lifter. I will now describe how all these functions are controlled by a single positively-operated medium.

F is a cock tapered throughout its length and held snug in conical opening CL4 by a stuffing-box f. A rod f extends upwardly from this cock and is fitted with a handle f2. This cock is centrally divided into upper-and lower chambers f3 f4 by a horizontal partition f5, the upper being the steam chamber and the lower the overow chamber. Extending transversely through the latter is the deliveryport f6, which is formed in a web depending from partition f5. This port f6 when in line with the delivery-tube of the forcer opens up communication between the latter and the outlet to the boiler. In one side of the cock is an overflow-port in the form of a deep groove or cut-away f7, which opens into the chamber f4 and is designed to receive the overliow from the discharge-chamber and delivery-tube of the forcer. Beneath this port is a second port f8, which allows the overflow from the channel d6 to pass into the cock and thence to the atmosphere. Thus it will be seen that all overow reaches the atmosphere through the ports in the lower chamber of the cock.

In the upper part of the cock are formed two oblong ports g g', one above the other, the former being designed to register with the steam-inlet a and the latter with the steamchannels 197 and E. The outlet-port g' is made slightly larger than the receiving-port. I have shown the cock formed with two sets of these steam inlet and outlet ports, thereby enabling the apparatus to be operated by turning the cock either to the right or to the Until the column of steam and water is established the boiler-outlet is tightly closed by the cock F; but even when the deliveryport first approaches coincidence with the forcer and boiler-outlet no communication is established between the latter and the over- Iiow. I-Ience there can be no deleterious results from boiler back pressure.

TOO

IIO

In operation when the cock F occupies the first position (indicated by Fig. 8) steam admitted to the inlet a is prevented from entering the injector by means of said cock; but when partly turned (see third position) steam will pass into the steam-chamber of said cock and out through port g' into one of the channels hi, supplying steam to the lifter, the channel E being closed. As the steam passes through Athe lifter-tubes and down through water-chamber d'1 and channel d6 it will enter the overflow-chamber of cock F through port fs, and upon reaching the atmosphere will entrain the air and steam from the injector, creating a vacuum in the waterchamber of the lifter, so that water will be drawn to the lifter. No steam being yet admitted to the forcer, there is no back pressure to retard the lifting of water. The waterbeing taken up by the steam-jet will .be discharged into chamber h6 and passing downward to the forcer will escape to the atmosphere through channel (Z6 and chamber d8, with which register the lower and upper overlow-ports, respectively, of the cock. The converging tubes and the overflows concentrate the column of steam and water and increase its v elocity in the combiningtube of the lifter, thereby rendering further overflow for the lifter unnecessary. Thereupon by giving the cock a st-ill further turn (see fifth position, Fig. 8) the lower port g will be brought into line with steam-channel E, allowing steam to enter the forcer, and at the same time the cock will partly close the overlflow from channel di", but any back pressure `can still iind outlet through the overflowports of the cock to such an extent as not to interfere with the water and steam concentrating and entering the combining and delivery tubes of the forcer. A further turning of the cock closes entirely the lower overflow, (see sixth position, Fig. 8,) and the full head of steam being admitted to channel E and the column having attained its full velocity the upper overiiow is closed through port f7, and the delivery-port f6 is gradually brought into line with the delivery-tube of the forcer and the boiler-outlet. The forcer being now fully supplied with steam and all overflow cut off, the cock is further turned, (see seventh position, Fig. 8,) opening up communication with the second steam-channel 117, leading to the lifter, thereby increasing the steam-supply to the lifter and making the now established column powerful enough to enter the boiler through the now fullyopened delivery-port in the cock. A still further turning of the cock (see eighth position,

Fig. S) will close one of the steam-channels leading to the lifter, thereby reducing the head of steam to the lifter, and consequently reducing the lifting power and hence capacity of the apparatus.

From what has been said the advantages of my invention will be apparent. In the first place it will be observed that the lifter performs its duty entirely independent of and free from any interruption by the forcer. The supply of steam to the lifter is independent of that to the forcer, although controlled by a common agency-to wit, the single cock. This cock not only controls the steam-supply to both the lifter and forcer, but also regulates the capacity of the machine. By arranging the cock in the manner stated I am enabled to start, work, and regulate the injector by a single device. As the cock is the only movable part employed in the construction of the injector, the latter is not liable to readily get out of order, nor is it possessed of any parts liable to suffer from the action of steam and water.
